    This is a merge of bigASP and LUSTIFY, which, in my opinion, are the best non-Pony SDXL checkpoints for NSFW images. This merge produces results similar to bigASP but with improved image quality and aesthetics.

    Very useful merge with bigasp !, I hope you can take a look at Natvis 2.7 for futures merge tho

    Seems to create a good image, only to massively oversaturate it with bright colors near the end.

    But judging by what other have made with it, i'm probably just being a dumbass with my settings.

    Not that i know what any of the settings in SD do lol

    Whats your settings?, remember that bigasp need some specific stuff, for example cfg at 3 and at the beginning of the prompt you must add "score_7_up"

    fhaifhaiDec 19, 2024

    first step would be to decide what program you want to use:


    - Forge (most beginner friendly)
    - Automatic1111 (the standard for many)
    - ComfyUI (superior control, not very beginner friendly)


    you will find tons of good tutorials on how to set up each of the above on youtube! And if you are really lazy and don't know much about computers, use Pinokio.

    Great model. very realistic and cappable.
    however it just keep ignoring every negative prompt towards SFW added. I find very hard to prompt something where it wont always generate naked ass/pants down.

    tetonasenjoyerMar 15, 2025· 3 reactions

    Too many dislikes towards a very precise comments. The checkpoint is AMAZING for NSFW images, but it is almost impossible to generate full SFW stuff. Sometimes you want to generate teasing images, instead of full NSFW stuff, and a few adjustments to the checkpoint in order to achieve such thing would be amazing.

    klapperklausMay 31, 2025

    if you use dmd2 and have a cfg of 1 negative prompts are ignored. you can try increment cfg to 1.1 or 1.2 and hope that it takes your negative prompt into accountwithout burning your image. you can edit the config files of forge and automatic1111 to get more control over how fine you can adjust the sliders.

    Download sdxl.vae.safetensors to the VAE folder.

    Use high score numbers in the positive prompt (eg. score__7_up) and low score values in the negative prompt (eg. score_1, score_2 etc). Use further negative text such as 'deformed, mutated, logo' etc.

    DPM++ 2M SDE for sampling and CFG Scale of 4.

    Use common SDXL dimensions such as 1024x1024 and 896x1152.

    @peenusbutter Those settings are bare minimum and are already on civitai, what I mean are technical specifications like optimal samplers and prompts to evoke different styles etc. No one should be post models so vaguely. But its all good, I figured out what is working nicely with this model.

    blaquaApr 26, 2025· 2 reactions

    @ShartHouse From the BigASP page "Finally, scoring. bigASP 🐍 v2, like v1 and inspired by the incredible work of PonyDiffusion, was trained with "score tags". This means it understands things like score_8_up, which specify the quality of the image you want generated. All images in bigASP's dataset were scored from 0 to 9, with 0 completely excluded from training, and 9 being the best of the best. So when you write something like score_7_up at the beginning of your prompt, you're telling bigASP "I want an image that's at least a quality of 7."

    Many people generate first pass in Pony for its creative and expressive scenes. Then do a second pass like Lustify or BigLust to bring out the realism.

    GaudiTechJul 8, 2025· 1 reaction

    @damiang This. it isn't completely monkey see monkey do. the "KitBash" or what have you gets very good results. I often mess with models here then throw the generated images onto my local machine and img2img with flux or another model without onsite generation. pony is also so much less buzz than flux so I think it is smart to start there.

    YSCyscOct 21, 2025

    This is a merge of bigASP and LUSTIFY.And if you read the Features of bigASP,

    this model understands quality scores to help improve generations, e.g. add score_7_up, to the start of your prompt to guide the quality of generations. More details below.

    TaurondirDec 3, 2025· 2 reactions

    Only PNG Images can contain extra MetaData in the form of JSON Code because only PNG files have support for extra data fields for storage, so if you drag a JPG, nothing will ever happen. Any PNG on CivitAI will contain SOME extra data, usually some settings like Steps, CFG, Sampler Name etc, but only SOME OTHERS will contain a full JSON Workflow that ComfyUI can pull from. There is an AddOn for Firefox called "Image Metadata Viewer" - I assume other browsers might have something similar - that you can use to right click an any image in your browser window to see the MetaData. After you do that a few times you will learn exactly what to look for, which is a bit more convenient then having ComfyUI always open to drag test images into.
